Crossthreaded Spark Plug

[Shane]

I had my spark plugs done last time at a shop (It was cold outside, and I was lazy).

Well, I went out to do them today, and the Drivers Side spark plug farthest back seems to be cross threaded. I didn't want to tug too hard, I was afraid to break it. I can't get it out, and even if I do I'm worried that I might not be able to put another one back in.

Any ideas?

Lube it excessively. Then try turning it back and forth in 1/8 turns, just working it little by little. Try to make progress loosening it, when it feels like it gives, loosen a little more and keep repeating this. I've removed several bolts this way without breaking off. Probably need to run a thread chaser through it and vacuum out the hole somehow.

Thanks, I will try that. Any more suggestions?

when you chase the threads out put grease on the thread chaser so that catches most of the the metal it removes
